We could have a chat without a browser, like Steem did.. A blockchain email system would be good. I use protonmail for my email for the encryption and security, but a blockchain email would be nice. It's probably tricky to do though. I know Dan Latimer talked about it when he was working on eos.. I just think as much teaming up as a crypto company like Hive can do with other crypto companies, without sacrificing freedom or stability.. is a good thing.
